Health alerts for bank holiday weekend as record May heat forecast in UK

The UK is preparing for a record-breaking May heatwave over the bank holiday weekend, with temperatures expected to reach as high as 33°C (91°F) in southern England and the Midlands. Amber heat health alerts have been issued for the East Midlands, West Midlands, the east of England, London, and the south-east, effective from Friday afternoon until Wednesday evening. These alerts warn of potential risks to life, property damage, significant travel delays, and power outages. Yellow alerts have also been issued for northern and southwestern England, highlighting health risks for vulnerable populations, particularly those over 75 or with pre-existing conditions. The forecasted temperatures could surpass the previous May record of 32.8°C, set over 80 years ago in parts of London, West Sussex, and Kent. Friday already marked the hottest day of the year so far, with Heathrow Airport recording 26.9°C. The heatwave is driven by a shift in wind patterns, with the jet stream moving northward and bringing warmer air from southern Europe. This weather comes after one of the driest Aprils on record in central and southern England, resulting in below-normal river levels and raising concerns about drought conditions. The Met Office deputy chief forecaster, Steve Kocher, noted that temperatures will rise steadily through the weekend, with 30°C expected on Saturday, 32°C on Sunday, and a peak of 33°C on Monday. The heatwave is likely to break both May and spring temperature records in the UK. While much of the country will experience dry and sunny weather, Northern Ireland and western Scotland may see more cloud cover and some showers. Coastal areas in the west could also experience low cloud and sea fog due to relatively cool sea surface temperatures. The extreme heat poses challenges for public health and infrastructure, with authorities urging caution, especially for vulnerable groups. The combination of high temperatures and dry conditions increases the risk of heat-related illnesses and may strain health and social care services. Additionally, the hot weather is expected to cause long traffic queues, exacerbated by extra border checks during the busy holiday period.
